Suggestion for Panasonic

The app works brilliantly. It seems the only reviews are from people who cant figure it out. But Panasonic if you read this I have a suggestion that would make it six out five stars. Please could you make the up volume button of the connected device control the shutter release. The shutter release needs a tactile feel so the photographer can be looking at the subject and not the device. Doing so now makes it hard to find the shutter release button your finger cant feel it on the screen.
Please and thank you.
